Abstract. Vertical profiles of aerosol and gas phase species were measured on flights near Hawaii on April 9 and 10, 1999, during NASA' s Pacific Exploratory Mission (PEM) Tropics B program. These measurements characterized aerosol microphysics, inferred chemistry, optical properties, and gases in several extensive dust and pollution plumes, also detected by satellites, which hart 1 o,ooo-gan trajectories back to sources in Asia. Size-resolved measurements indicative of aerosol sulfate, black carbon, dust, light scattering, and absorption allowed determination of their concentrations and contributions to column aerosol optical depth. A new Chemical Transport Model (CTM) that includes aerosol, meteorological fields, dynamics, gas and particle source emissions, a chemistry component (MATCH), and assimilated satellite data was used to predict aerosol and gas concentrations and the aerosol optical effects along our flight path. Flight measurements confirmed the "river-like" plume structures predicted by the CTM and showed close agreement with the predicted contributions of dust and sulfate to aerosol concentrations and optical properties for this global-scale transport path. Consistency between satellite, model and in situ assessment of aerosol optical depth was found, with noted exceptions, within •25%. Both observations and model results confirmed that this aerosol was being entrained into the marine boundary layer between Hawaii and California where it can be expected to modify the type and concentration of cloud condensation nuclei in ways that may alter properties of low-level clouds. These observations document the significance and complexity of long-range aerosol transport and highlight the potential of emerging CTM models to extend observational data and address related issues on global scales.

“…By assuming an aerosol model (i.e., specification of a particular mixture), it is possible using RT theory to derive a one-to-one relationship between observed radiance and aerosol column amount. Such modeling has been applied to the retrieval of aerosol concentration from Landsat [16], [17] and National Oceanic and Atmospheric Administration (NOAA) AVHRR [5], [18]- [21] single-view radiances. Multiangle radiances, which are governed strongly by the shape of the aerosol scattering phase function, provide additional information with which to refine the aerosol model used in the retrieval of optical depth [22].…”

“…The most extensive climatology available today uses solar reflectance measured by Advanced Very High Resolution Radiometer (AVHRR) and has provided coverage of the world's oceans equatorward of 70 latitude since 1987 [5]. Although this climatology is very useful and offers some interesting insights into global aerosol processes, it has two major deficiencies.…”

Abstract-Aerosols are believed to play a direct role in the radiation budget of earth, but their net radiative effect is not well established, particularly on regional scales. Whether aerosols heat or cool a given location depends on their composition and column amount and on the surface albedo, information that is not routinely available, especially over land. Obtaining global information on aerosol and surface radiative characteristics, over both ocean and land, is a task of the Multi-angle Imaging SpectroRadiometer (MISR), an instrument to be launched in 1998 on the Earth Observing System (EOS)-AM1 platform. Three algorithms are described that will be implemented to retrieve aerosol properties globally using MISR data. Because of the large volume of data to be processed on a daily basis, these algorithms rely on lookup tables of atmospheric radiative parameters and predetermined aerosol mixture models to expedite the radiative transfer (RT) calculations. Over oceans, the "dark water" algorithm is used, taking full advantage of the nature of the MISR data. Over land, a choice of algorithms is made, depending on the surface types within a scene-dark water bodies, heavily vegetated areas, or high-contrast terrain. The retrieval algorithms are tested on simulated MISR data, computed using realistic aerosol and surface reflectance models. The results indicate that aerosol optical depth can be retrieved with an accuracy of 0.05 or 10%, whichever is greater, and some information can be obtained about the aerosol chemical and physical properties.

“…Due to their impact on light, their monitoring from space is performed in a visible part of the spectrum, which means that is possible only in the daytime and in cloudless areas. Standard algorithms used to determine the aerosol optical thickness (AOT) are based on data from a single spectral channel of the AVHRR (Advanced Very High Resolution Radiometer) [9]. The data of AOT that are used to determine Ta (eq.…”
